KC's casinos are spending millions to pummel voters with last-minute TV, print and radio ads aimed at passing Proposition A. Here's one final hope that Missouri voters reject the costly measure today.

The ad campaign is a hopeful sign: Casinos must have a poll showing that Missourians still need to be convinced that the state needs to be opened to a lot more gambling.

That poll also may show that Missourians aren't falling for casinos' claim that they will produce more money for the state's schools.

As I have noted before, many school districts -- including Kansas City, Independence and Center in our area -- won't get any more money up front if Proposition A passes.

Missouri doesn't need wide-open gambling, and the defeat of Proposition A would be a good move for the state.
